Cytoplasmic DNA. Berthou et al. (1980, 1983) have applied methods of identifying DNA of cytoplasmic organelles (chloroplasts and mitochondria) to coffee. Such methods include separation by electrophoresis on agarose slab gels of fragments of DNA obtained by bacterial restriction enzymes. Electrophoresis of fragments of chloroplast DNA, obtained by the Hpa II enzyme (from Haemophilus parainfluenzae) suggest that the following species have a similar origin: C. arabica and C. eugenioides; C. caneph ora, the Nana taxon and C.

Stenophylla tend to flower later: the time interval between a flowering inducing rainshower and anthesis is also often one day longer for C. canephora than for C. iberica. Clearly, studies of wild coffee populations have contributed considerably to a better understanding of the relation between species of multispecific associations. Genetic exchange between coffee species through interspecific hybridisation should be taken into account when formulating theories on the evolution of coffee species.
